Ah yes didn't read thatHe did say for the lid.
That looks good with the tails all ferruled, i think I will be doing that myselfCut and ferrule for me every time.
Like to leave a little bit length still so the RCBO isn't completely useless if it does need to be moved a little in the future.

Regs don't require ferrules be fitted.
They require the fine stranded wire be protected against damage from the screw terminals which can be satisfied by twisting and then doubling over the strands.
Think the regulation is every connection shall have adequate mechanical strength and be suitable for the terminal or something along those lines

So there must be hundreds of thousands of 13 amp plugs which don't comply then ?!
Regardless of which rules and regulations they fall under I'm talking about fine stranded flexible copper cable tightened with a screw terminal and without further 'treatment' , and with absolutely no ill effects.
I believe that regulation regards fine wire only.
It's upto the installer to be satisfied that the connection made is electrically sound and is suitable terminated.
If worried about crushing then use a torque screwdriver to manufacturers instructions
Yes there are a lot of fine stranded cables terminated in screw terminals with no ill effects, but there are also a lot which have failed as a result of it.
I find it hard to believe that you have never encountered a flexible conductor which has been damaged by the tightening of a screw terminal.
any plug fitted by a manufacturer or supplier of appliances will have ferrules used on the flex, all of the equipment which we get new with a fitted flex has ferrules on the end ready for connection.
The standards which apply to equipment building, panel building etc all require ferrules.
Should we all just stick our heads in the sand and resist simple changes which make things just a little bit better?
